Ask HN: Can we sell something on HN?

I had this question from a long time and wanted to ask the community regarding it - I had purchased a domain and started working on a side project but got side tracked. Is it okay to sell it on HN? Lots of devs go through the site each day and I'm sure someone would find the project interesting.

I agree that there are sites like sedo, flippa and 1kprojects (now indiemaker) but they are not as easy as submitting something to HN and waiting for an offer.
